Abstract

Selon la présente invention, un dispositif sans fil reçoit des informations de commande de liaison descendante (DCI), dans une occasion de surveillance de canal de commande, pour programmer des blocs de transport (TB) dans des tranches de temps de liaison descendante. Chaque DCI des DCI : planifie un TB respectif, des TB, dans une tranche de temps de liaison descendante des tranches de temps de liaison descendante ; et indique un même intervalle de temps de liaison montante de la transmission d'informations sur l'accusé de réception du TB respectif. Une détermination est faite, dans un livre de codes d'accusé de réception, aux emplacements des informations sur l'accusé de réception des TB, en fonction des temps de démarrage des intervalles de temps de liaison descendante. Un livre de codes d'accusé de réception est transmis.
